Centos服务器搭建（2）——安装tomcat

首先已经安装完JDK

1.下载apache-tomcat-7.0.57.tar.gz

2.复制到/opt 解压

[root@iZ2873rjubzZ opt]# cp /root/apache-tomcat-7.0.57.tar.gz /opt/
[root@iZ2873rjubzZ opt]# tar -xzvf apache-tomcat-7.0.57.tar.gz

3. 设置环境变量

[root@iZ2873rjubzZ opt]# vi /etc/profile
##shift+g定位到文件末尾，添加以下代码
export CATALINA_HOME=/opt/apache-tomcat-7.0.57
export JAVA_HOME PATH CLASSPATH
##执行以下命令让配置文件生效
[root@iZ2873rjubzZ opt]# source /etc/profile

4.启动tomcat

[root@iZ2873rjubzZ opt]# apache-tomcat-7.0.57/bin/startup.sh
Using CATALINA_BASE:   /opt/apache-tomcat-7.0.57
Using CATALINA_HOME:   /opt/apache-tomcat-7.0.57
Using CATALINA_TMPDIR: /opt/apache-tomcat-7.0.57/temp
Using JRE_HOME:        /opt/jdk1.7.0_51
Using CLASSPATH:       /opt/apache-tomcat-7.0.57/bin/bootstrap.jar:/opt/apache-t
omcat-7.0.57/bin/tomcat-juli.jar
Tomcat started.

通过http://localhost:8080 访问有没有启动成功

5. 关闭tomcat

[root@iZ2873rjubzZ opt]# apache-tomcat-7.0.57/bin/shutdown.sh
Using CATALINA_BASE:   /opt/apache-tomcat-7.0.57
Using CATALINA_HOME:   /opt/apache-tomcat-7.0.57
Using CATALINA_TMPDIR: /opt/apache-tomcat-7.0.57/temp
Using JRE_HOME:        /opt/jdk1.7.0_51
Using CLASSPATH:       /opt/apache-tomcat-7.0.57/bin/bootstrap.jar:/opt/apache-t
omcat-7.0.57/bin/tomcat-juli.jar
[root@iZ2873rjubzZ opt]#

6 设置开启启动

进入编辑
vi /etc/rc.d/rc.local

打开后在最底部复制下面

export JDK_HOME=/opt/jdk1.7.0_51
export JAVA_HOME=/opt/jdk1.7.0_51
/opt/apache-tomcat-7.0.57/bin/startup.sh

 7.添加tomcat管理用户

[root@dev ~]# vi /opt/apache-tomcat-7.0.57/conf/tomcat-users.xml

最下面添加
  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <role rolename="manager-jmx"/>
  <role rolename="manager-status"/>
  <user username="tomcat" password="s3cret" roles="manager-gui,manager-jmx,manager-script,manager-status"/>

8.增大tomcat 启动内存

打开文件
[root@dev ~]# vi /opt/apache-tomcat-7.0.57/bin/catalina.sh

注释下的第一行 添加
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=512m"

至此 tomcat已经安装完成
